The boys debuted with 'Spring Up' last year, came back in the summer with 'Summer Vibes', and then again in the fall with 'Autumn Story'. They're now bringing the series to a close with 'Winter Dream' and title song "Should've Held On". The single includes two other songs - "Cotton Candy" and "You & Me (Thanks AROHA)". The last song is a fan song with lyrics by the entire group.
ASTRO will also be celebrating their 1st anniversary since debut this February 23.
